Laser microdrilling is a common micromachining operation in many industrial applications. This paper presents a new laser microdrilling technique in which a hollow-core fiber is employed to transmit femtosecond laser pulses ...

Curing duration and target temperature are the most critical process parameters for
high- pressure hose products. The air temperature collected in the curing chamber is represented in the form of a profile. A proper ...

Drilling is involved in many applications of carbon fiber reinforced plastic (CFRP) composite. Twist drilling is widely used in industry. Rotary ultrasonic machining (RUM) has been successfully tested to drill holes in ...

Carbon fiber reinforced plastic (CFRP) composites are very difficult to machine. A large number of holes need to be drilled in CFRP for many applications. Therefore, so it is important to develop cost-effective drilling ...

Carbon fiber-reinforced polymer (CFRP) has been widely used in aircraft components, automotive parts, and sporting goods. Hole machining is the most frequently employed operation of secondary machining for fiber-reinforced ...

Drilling is involved in many applications of carbon fiber reinforced plastic (CFRP)
composites. Rotary ultrasonic machining (RUM) has been successfully employed to drill holes in CFRP using either cutting fluid or cold ...

Knowing cutting force in rotary ultrasonic machining(RUM)can help optimizing input variables.RUM of brittle materials has been investigated both experimentally and theoretically.However,there are no reports on cutting force ...

Size reduction is the first step for manufacturing biofuels from woody biomass. It is usually performed using milling machines and the particle size is controlled by the size of the sieve installed on a milling machine. ...
